[tex] \frac{237}{10} = 23 \frac{7}{10} [/tex]

Answer:

the slope is -1/3

the Y intercept is 10/3

Step-by-step explanation:

Answer:

-1/3

Step-by-step explanation:

We want to get the equation in slope intercept form (y=mx+b)  where m is the slope and b is the y intercept

x+3y = 10

Subtract x from each side

x-x+3y = -x+10

3y = -x+10

Divide each side by 3

3y/3 = -1/3x +10/3

y = -1/3x +10/3

The slope is -1/3 and the y intercept is 10/3

I am very good at Pythagorean theorem I did it this year.

To do this it is actually like the easiest thing to do in math. The formula is A²+B²=C². To do this it is easier with a scientific calculator. If you don't have one you can use this online calculator: desmos.com/scientific

Step 1. get the two number and square (²) them ( multiply that number by it) For Example 30 multiplied by 30. Or on the calculator I gave you just do 30²+40²

Step 2. After that you will get 2500. Then on the calculator get this symbol √ and but the number 2500 in front of it. it should look like this. √2500.

Step 3. After that you will get 50 which is your answer. And that is how you do Pythagorean theorem.

Answer:

The mean would be 14.4 hours.

Step-by-step explanation:

In order to find the mean, or average, of the numbers, you would add all the numbers together.

17 + 15 +14 + 14 + 12 which equals 72

Then, you take the total which is 72, and divide it by how many numbers you added together which is 5.

72/5 = 14.4

Answer:

14.4

Step-by-step explanation:

To find the mean in math, you add all of your numbers together, the divide by how many numbers you added together. So add 17,15,14,14, and 12 together to get 72. Divide 72 by 5 to get 14.4

The measure of angle A can be calculated using trigonometry and the components of a known vector. The relationship of the components forms a right triangle, the properties of which can be used to find the measure of angle A.

The measure of angle A can be calculated using trigonometry if we know the distances from the problem. By knowing the scalar components Ax and Ay of vector A, we can find its magnitude and direction angle. In this case, the direction is the angle the vector forms with the positive direction on the x-axis, measured in the counterclockwise direction. The lengths A, Ax, and Ay form a right triangle, related by the Pythagorean theorem.

If the vector A is known, then its magnitude A and its angle are known. To find Ax and Ay, we use the following relationships for a right triangle: Ax = Acose. If the vector lies in the first or the fourth quadrant, where component Ax is positive, angle A is identical to the direction angle. Conversely, when the vector lies in the second or third quadrant, where component Ax is negative, the direction angle is A = 0 + 180°.

The measure of angle A in the given figure is equal to 20 degrees.

To solve this question we can use the property of a triangle that the sum of all angles in a triangle is equal to 180 degrees.

We have been given three different angles in this figure which are: 90 degrees, 71x-1, and 20x.

Let us find the value of x before finding the value of angle A

71x-1 + 20x + 90 = 180

71x + 20x = 180 - 90 + 1

91x = 91

x = 1

Now we can calculate the value of angle A as:

20x

= 20 (1)

= 20 degrees

Answer:

Step-by-step explanation:

The given function is

We add and subtract the square of half the coefficient of x.

[tex]h(x)=x^2-8x+(\frac{-8}{2})^2-(\frac{-8}{2})^2+14[/tex]

[tex]h(x)=x^2-8x+(-4)^2-(-4)^2+14[/tex]

Answer:

A

Step-by-step explanation:

Given the 2 equations

y = x² + 8x + 2 → (1)

y = 7x + 4 → (2)

Substitute y = x² + 8x + 2 into (2)

x² + 8x + 2 = 7x + 4 ( subtract 7x + 4 from both sides )

x² + x - 2 = 0 ← in standard form

(x + 2)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

Substitute these values into (2) for the corresponding values of y

x = - 2 : y = - 14 + 4 = - 10 ⇒ (- 2, - 10)

x = 1 : y = 7 + 4 = 11 ⇒ (1, 11)

The solutions are (- 2, - 10) and (1, 11) → A

Answer:  Option b.

Step-by-step explanation:

First, you need to calculate the ratio of the area. This is:

[tex]ratio=(\frac{64}{28})^2\\\\ratio=\frac{256}{49}[/tex]

You know that the area of the smaller trapezoid is 771 m², then you can set up the following proportion, where "x" is the area of the larger trapezoid. Then you have:

[tex]\frac{256}{49}=\frac{x}{771}[/tex]

Now you must solve for "x". Therefore, you get that the area of the larger trapezoid is:

 [tex]x=(771)(\frac{256}{49})\\\\x=4,028m^2[/tex]

To the nearest whole number, the area of the other similar figure is: b. 4,028 m².

The ratio of the areas of two similar figures equals the ratio of the square of their corresponding sides.

Thus:

Let x represent the area of the other figure.

Therefore:

771/x = (28²)/(64²)

771/x = 784/4,096

x = (771 × 4,096)/784

x = 4,028

Therefore, to the nearest whole number, the area of the other similar figure is: b. 4,028 m².

Answer:

C. [tex]y=\frac{5}{7}x+2[/tex].

Step-by-step explanation:

We have been given a scatter plot. We are asked to find the equation of line of best fit.

First of all, we will find slope of line of best fit using points [tex](0,2)[/tex] and [tex](7,7)[/tex].

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{7-2}{7-0}[/tex]

[tex]m=\frac{5}{7}[/tex]

We can see that y-intercept of line of best fit is 2.

We will write our equation in slope intercept form [tex]y=mx+b[/tex], where,

m = Slope,

b = The y-intercept.

Upon substituting [tex]m=\frac{5}{7}[/tex] and [tex]b=2[/tex] in slope-intercept form, we will get:

[tex]y=\frac{5}{7}x+2[/tex]

Therefore, the equation of line of best fit for given scatter plot is [tex]y=\frac{5}{7}x+2[/tex] and option C is the correct choice.

Answer:

[tex]\frac{2p-1}{3}[/tex]

Step-by-step explanation:

Since you want to get q only and q appears in both side of the equation. Try to isolate q to one side.

1) Expand 2(q+p)

2q + 2p = 1 + 5q

2) Move all q terms to one side

5q - 2q = 2p - 1

3q = 2p - 1

3) Divide 3 on both side (to isolate q)

q = [tex]\frac{2p-1}{3}[/tex]

After making q the subject of the formula in the equation 2(q + p) = 1 + 5q, the resulting solution is:

[tex]q = \frac{2p - 1}{3}[/tex]

The given equation is:

2(q + p) = 1 +5q

To make q the subject of the formula, follow the steps below

Expand the expression using the distributive rule

2q + 2p = 1 + 5q

Collect like terms by subtracting 2q from both sides of the equation

2q - 2q + 2p = 1 + 5q - 2q

2p = 1 + 3q

Subtract 1 from both sides of the equation

2p - 1 = 1 + 3q - 1

2p - 1 = 3q

Divide through by 3

[tex] \frac{2p - 1}{3} = q[/tex]

Therefore after making q the subject if the formula in the equation 2(q + p) = 1 + 5q, the resulting solution is:

[tex] q = \frac{2p - 1}{3}[/tex]

The electric force of a charged balloon sticking to the ceiling is due to the interaction between the balloon and the induced positive charge in the ceiling. This force is related to the principle of electrostatics and can theoretically be calculated using Coulomb's Law, but would require more details. However, for the balloon to remain stuck to the ceiling, this electrostatic force must be greater than the weight of the balloon.

To calculate the electric force of a charged balloon sticking to the ceiling, you first need to consider the scenario as an interaction between the charged balloon and the induced charge in the ceiling. This scenario is related to the principle of electrostatics, where like charges repel and different charges attract. It is the electrostatic force that is making the balloon stick to the ceiling.

The balloon gets charged by picking up extra electrons (negative charge) when rubbed. When brought near the ceiling, these extra electrons in the balloon repel the electrons in the ceiling, causing the area of the ceiling near the balloon to be positively charged. This induced positive charge in the ceiling then attracts the negatively charged balloon. The force between the balloon and the ceiling can be caluclated using Coulomb's Law, which states that the force between two charges is directly proportional to the product of their charges, and inversely proportional to the square of the distance between them. However, to accurately calculate this force using Coulomb's law, we need more information such as the amount of charge on the balloon and the distance from the balloon to the ceiling.

Finally, for a balloon to stick to the ceiling, the electrostatic force must be greater than the weight of the balloon. The weight of the balloon can be calculated using the formula Weight = mass x gravity. In this case, the mass of the balloon is 0.020kg and the gravitational force is approximately 9.8 m/s². Therefore, the weight is 0.020kg x 9.8 m/s² = 0.196N. So for the balloon to stick to the ceiling, the electrostatic force must be greater than 0.196 N.
